Sure, i've already started reworking and cleaning major parts of the PKGBUILD (of cause using maps-sync etc).
Btw this is really only a bleeding-edge dev version package of ufoai, there is a stable release in community :)

Can you explain what you mean by "driver issues" as why you disowned the package?
This is really a great linux game and I'm hoping that the new maintainer (anthraxx) will continue to keep this package up to date.

Also, the maps do take forever to build, even on fast machines, so I recommend we implement hollunder's suggestions ('make maps-sync' instead of 'make maps')

Also I think line 39: 'cd $_gitname' should be removed, as we are already in that diretory and build fails.
